Abstract

Abstract The present invention provides a method for obtaining an image comprising the steps of: image-wise exposing to intense radiation a heat mode recording material comprising on a support (i) a donor layer containing an image forming substance capable of being transferred upon heating to an image receiving material, (ii) a barrier layer being impermeable for said image forming substance and overlaying said donor layer, and (iii) a light-to-heat converting substance, capable of absorbing the light used for exposing said heat mode recording material and releasing the absorbed energy under the form of heat, rubbing, under dry conditions or with the aid of a non-solvent for the barrier layer, the thus obtained image-wise exposed heat mode recording material to remove said barrier layer at the exposed parts and overall heating the exposed heat mode recording material whilst in contact with an image receiving material thereby causing an image-wise transfer of said image forming substance to said image receiving material.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 175 words
A method for obtaining an image comprising the steps of: image-wise exposing to intense radiation a heat mode recording material comprising on a support (i) a donor layer containing an image forming substance capable of being transferred upon heating to an image receiving material, (ii) a barrier layer being impermeable for said image forming substance and overlaying said donor layer, and (iii) a light-to-heat converting substance, capable of absorbing the light used for exposing said heat mode recording material and releasing the absorbed energy under the form of heat, said light-to-heat converting substance being present in said barrier layer or in a separate layer between said donor layer and barrier layer, rubbing, under dry conditions or by means of a non-solvent for the barrier layer, the thus obtained image-wise exposed heat mode recording material to remove said barrier layer at the exposed parts, and overall heating the exposed heat mode recording material while in contact with an image receiving material thereby causing an image-wise transfer of said image forming substance to said image receiving material.
Claim 2
Independent Claim 175 words
A method for obtaining an image comprising the steps of: image-wise exposing to intense radiation a heat mode recording material comprising on a support (i) a donor layer containing an image forming substance capable of being transferred upon heating to an image receiving material, (ii) a barrier layer being impermeable for said image forming substance and overlaying said donor layer, and (iii) a light-to-heat converting substance, capable of absorbing the light used for exposing said heat mode recording material and releasing the absorbed energy under the form of heat, said light-to-heat converting substance being present in said barrier layer or in a separate layer between said donor layer and barrier layer, rubbing, under dry conditions or by means of a non-solvent for the barrier layer, the thus obtained image-wise exposed heat mode recording material to remove said barrier layer at the exposed parts, and overall heating the exposed heat mode recording material while in contact with an image receiving material thereby causing an image-wise transfer of said image forming substance to said image receiving material.
Claim 3
Dependent Claim 15 words
A method according to claim 1 wherein said barrier layer contains a hardened silicone resin.
Claim 4
Dependent Claim 26 words
A method according to claim 1 wherein said light-to-heat converting substance is contained in a separate recording layer located between said barrier layer and donor layer.
Claim 5
Dependent Claim 19 words
A method according to claim 3 wherein said recording layer has a thickness of not more than 3 μm.
Claim 6
Dependent Claim 14 words
A method according to claim 1 wherein said donor layer is a thermoplastic layer.
Claim 7
Dependent Claim 16 words
A method according to claim 1 wherein said image forming substance is a thermally transferable dye.
Claim 8
Dependent Claim 74 words
A heat mode recording material comprising on a support in the order given a donor layer containing an image forming substance capable of being transferred upon heating to an image receiving material, a recording layer containing a light-to-heat converting substance capable of absorbing the light used for exposing said heat mode recording material and releasing the absorbed energy under the form of heat and a barrier layer being impermeable for said image forming substance.
Claim 9
Dependent Claim 74 words
A heat mode recording material comprising on a support in the order given a donor layer containing an image forming substance capable of being transferred upon heating to an image receiving material, a recording layer containing a light-to-heat converting substance capable of absorbing the light used for exposing said heat mode recording material and releasing the absorbed energy under the form of heat and a barrier layer being impermeable for said image forming substance.
Claim 10
Dependent Claim 22 words
A heat mode recording material according to claim 7 wherein said recording layer has a thickness of not more than 2.5 μm.
Claim 11
Dependent Claim 20 words
A heat mode recording material according to claim 7 or 8 wherein said barrier layer contains a hardened silicone resin.
